George North knows from first-hand experience just how tough a proposition Australia could be for the British and Irish Lions next month.

The 21-year-old Wales wing has already achieved a prodigious amount in his rugby career, having been part of two RBS 6 Nations title-winning teams and reached a World Cup semi-final. Australia, though, have refused to play ball, with North still to taste victory against the Wallabies in five attempts.

"I think we have had our bad time now," North said. "It was unfortunate to lose those last four Tests by an average of something like three points. It was horrible, and I think we learnt our lesson."

"Australia are a physical team and they have a pretty star-studded back-line. What haven't they got? They've got speed, hands and physicality. They have got everything there - strength in depth as well.

"You always do your best, and unfortunately, the results marginally didn't go our way, but there is nothing to fear. We could have won four of those last five games.

"It has been frustrating, we have been so close on a number of occasions. Whatever Test side they (Australia) put out will be a difficult one to play against."

North's selection for the Lions came just 17 days after his 21st birthday, and he is rated a very short price to make the Test team, providing further evidence of how far he has progressed in such a short period of time.

"It (Lions squad selection) was a bit of a nervous time, but when I heard my name it was the best feeling in the world," he added.

"When the selection was announced it was pretty awesome, surreal, but when we met up in London last week it really sunk in. It was the first time the boys had met and been all together. It was a funny sort of feeling.

"You kind of realise where you are when you're trying on your suits and stuff and you are sat between Paul O'Connell and Conor Murray, and there is Sam Warburton and Manu Tuilagi as well. You realise it's kind of a big deal after that. It has been a long season, but hopefully we will finish it with a sweet win."
